It could be useful in a routing table:

Destination  Gateway      Genmask         Flags Metric Ref    Use Iface U     0      0        0 eth1   U     0      0        0 eth0         UG    0      0        0 eth0

The destination could do the same in reverse, so the conversation would 
only be between those two systems.
